at&t htc 8x MMS

Anyone know how to manually set up the MMS for this phone to work with simple mobile. Connection set up doesn't want to start. It keeps giving me that no database is found for my phone. I hope someone has an idea of why it isn't working.

Wish I could help but I've got a Verizon 8x. On a related note, mine and my wife's phones both stopped being able to send and receive mms and SMS last week. I'm starting to regret using my upgrade on another HTC. Plagued with issues
